Apple Watch Sport 42mm Space Grey Aluminum Case With Black Sport Band

Apple Watch represents a new chapter in the relationship people have with technology. It’s the most personal product Apple's ever made, because it’s the first one designed to be worn. It’s an incredibly accurate timepiece. A device that helps you stay on schedule, in touch, and headed in the right direction. And a health and fitness companion that never stops thinking of ways for you to be more active and fit. Apple Watch is all these things. Which makes it so much more than just a watch. But precisely what we think a watch should be.

An incredibly precise timepiece.

High-quality watches have long been defined by their ability to keep unfailingly accurate time, and Apple Watch is no exception. It uses multiple technologies in conjunction with your iPhone to keep time within 50 milliseconds of the definitive global time standard. Apple Watch continually checks against the definitive global time standard with the same precision found in GPS satellites. If you move from one time zone to another, Apple Watch automatically adjusts. When daylight saving time begins, Apple Watch simply changes to the new time. So you never once have to set it yourself. Apple Watch also presents time in a more meaningful, personal context by sending you notifications and alerts relevant to your life and schedule.

Not just a display, but the focal point of the whole experience.

A Retina display is the primary surface for every interaction with Apple Watch. And it’s clear why. The incredibly high pixel density makes numbers and text easy to read at a glance, even while you’re moving. Images and graphics render with remarkable sharpness and contrast, including finely detailed ones like the rotation of a hair-thin second hand on a watch face. And the display is extremely energy efficient, critical for a device you wear throughout the day.

Over two million ways to see time.

Apple Watch comes with a range of watch faces you can change whenever you like. You can also add specialized functions - known in watchmaking as complications - to most faces. Choose stopwatches, stock quotes, weather updates, and more. When you combine all the possible options, the opportunities for personalization are virtually endless.

Stay closer to the people you care about.

Messages, calls, and mail. Tailored for your wrist.Apple Watch adds a new dimension to the way you communicate. In just a glance it shows you who’s contacting you. It even gets your attention the way another person would - by tapping you. There are subtle audio cues, too. The experience is discreet and nuanced, with different types of notifications having their own unique character.

An intelligent health and fitness companion.

Apple Watch unites the capabilities of an all-day fitness tracker and a highly advanced sports watch in one device you can wear all the time. It can track a wider variety of activities because it’s able to collect more types of data. It uses an accelerometer to measure your total body movement. It has a custom sensor that can measure intensity by tracking your heart rate. And it uses the GPS and Wi‑Fi in your iPhone to track how far you’ve moved.

Workout App.

More detailed measurement when you need it most.Whenever you’re doing a dedicated cardio workout, use the Workout app built into Apple Watch. It shows real-time stats such as time, distance, calories, and pace. It lets you set goals for each workout, encourages you to meet or beat those goals along the way, and gives you a summary of what you’ve achieved. And your workout is included in your Activity app measurements for the day.
